HAND DIE-STOCK.

L censes.

To all whom it may concern.

"Be it known that I, GEORGE I-I. RAY, a

citizen of the United States,.residing at Belvidere, '1n the county ofBoone and State of Illinols, have invented certain new andusefnl.Improvements in Hand'Die-Stocks, of

. which the following is a specification.

The object of this invention is to provide .an automatic oiling devicefor hand op'er-- valve is open.. Fi is a section on. linea a Fig. 1, inwhich the valve is closed.

' Fig. 6 is a section on line b b Fig. 5.

'The hand die st 1: shown in the drawings, in the main sof an. oldconstruction t which I have'applied my improvements. Thehead hisprovided with sectional dies *2 and with a support for a collar 3. The.ends 4 and 5 are internally screw-threaded,

and the-end 4' is formed with a bottom 6. A

tubular-lever 7 has a screw-thread connec-,

tion' with the end 4, and a lever 8 has a screw thread connection withthe' end 5. Theerid 'of the tubular lever 7 is closed by a plug 9.

A screw 10 has a connection with the bottom 6 of the end 4 and istubular, a tubular the tubular screw 11.

screw 11 is turned in connection with the bottom 6 of the end 4 andforms a continuation oft-he screw 10. Between the screws 10 and 11 islocated a flexible washer 12.

A tube 13 is located in the tubular screws 10 and 11 and has a removablecap 14 connected-to one end and is adapted to be seated on the end ofthe. tubular screw 10 thereby acting as a valve. Thisatube near the cap"14 is formed with an;;.opening 15 communicating with the space 16in theupper end of the screw 10. 4 collar 17 is secured to the tube 13. Acoiled spring 18 surrounds the tube 13 having one end resting againstthe collar 17 and its other end resting against The action of thisspring'is to holdthe cap14 sealed against the end of the 'tubular screw10. The tube 13 has its end 19 bent at right angles to its V length andpointing toward the dies 2.

In use, the screw plug is removed and Specification of Letters Patent.Application filed March 25 1912. Serial No. 686,158.

the tubular lever 7 filled with oil, the cap 14 I resting against theend of the screw 10 will prevent the escape of oil from the lever.

y In placing the die stock on asection of pipe. 20 on which threads areto be cut, the end 19' of the tube 13. will contact with the pipesection thereby moving the tube lengthwise which will move the cap14free of its seat on the screw 10, thereby permitting the oil in thelever 7 to pass through the opening 15 into the tube 13 and escapethrough its bent end 19 onto the pipe section, each turn of the lever 7is brought into a vertical position over the pipe section, beingthreaded, oil Will escape on the pipe section, and the oil will flowback to the lever 7 when the lever is moved from this position.

'W hen the stock is not in use, it may be turned in any position as thecap will be seated, and the flow of oil cut oil.

I claim as my invention.

1. The combination of a hand die-stock, dies supported therein, areservoir supported thereby, a valve at the base of the reservoir, and atube connected to the valve, leading to the dies and so disposed", thatupon entering a pipe section into the die-stock to be threaded, saidpipe will automatically operate'said tube, unseating the valve andallowing a flow ,of oil from the reservoir to the dies. 1

2. The combination of a hand die-stock, dies supported therein, areservoir supported thereby, a valve seat at the base of the reservoir,a valve seated thereon, and a movable tuberigidly secured to said valve,leading to a point adjacent to the dies and forming an oil passage fromthe reservoir to the dies.

8. The combination of 'a hand die-stock, dies supported therein, areservoir supported thereby, a valve at the base of the reservoir, atube rigidly secured to the valve and leading to a point adjacent to the(lies, a spring adapted to hold the valve seated, and an opening in thetube adapted to communicate with the reservoir.

4. The combination of a hand die stock, dies supported therein, areservoir supported thereby, a valve at the base of the reservoir,a'tube secured to the valve, an opening in the tube adapted tocommunicate with the reservoir, and a spring adapted to hold thethatuponythreading a] pipe secti0n,1
